La reconstrucción

Artículo principal: Reconstrucción (Estados Unidos)

Entre 1865 y 1877 tiene lugar el período de la Reconstrucción, el cual se caracterizó por los intentos del gobierno de Washington de sanar las heridas de la guerra. Se modificó la constitución para otorgar libertad y derechos a los negros: A través de la Decimotercera Enmienda se prohibía la esclavitud, la Decimocuarta Enmienda extendía las protecciones legales federales a todos los ciudadanos independientemente de su raza y la Decimoquinta Enmienda abolía las restricciones raciales para votar.16​

La Reconstrucción no fue tarea fácil. Los políticos del sur pusieron en marcha las Leyes Jim Crow bajo el principio de Separados pero iguales. Por consiguiente, se estableció la segregación racial en todas las instalaciones públicas. Estas leyes afectaron a casi todas las instalaciones públicas y al transporte, incluidos los vagones de los trenes y autobuses interestatales. Las instalaciones para los afroamericanos y los nativos americanos eran consistentemente inferiores y carecían de fondos suficientes en comparación con las instalaciones para los estadounidenses blancos; a veces, no había instalaciones para los negros17​18​.

En 1865 se funda el Ku Klux Klan, una organización terrorista supremacista blanca que llevará a cabo violentos ataques contra la comunidad negra, los políticos favorables a la reconstrucción y los Carpetbaggers, los inmigrantes que llegaban al sur desde los estados del norte. Si bien el primer Ku Klux Klan fue disuelto por Ulysses S. Grant, a través del Acta de Derechos Civiles de 1871, el Klan reapareció a comienzos del Siglo XX. Las principales causas que explican el renacimiento de la organización eran la cada vez mayor inmigración, siendo el Klan una organización antisemita y anticatólica, el estreno en 1915 de la película El nacimiento de una nación de D. W. Griffith, la cual idealizaba al primer Ku Klux Klan, y el caso Leo Frank, un judío linchado en 1915 en Georgia tras ser acusado de violación y asesinato. El asesinato de Frank generó una oleada de antisemitismo por todo el país.

Where in the world, other than Newfoundland, is
Naya [18.7K]

Answer:

-India, Iran, Afghanistan, Myanmar, Sri Lanka, the Marquesas, as well as parts of Australia use half-hour deviations from standard time, and some nations, such as Nepal, and some provinces, such as the Chatham Islands of New Zealand, use quarter-hour deviations.

-This has largely to do with the politics in each of those places. For example, in New Delhi, India, they found themselves halfway between two meridians, and therefore decided to be 30 minutes between each, as opposed to adopting one time or the other

Meridians - a circle of constant longitude passing through a given place on the earth's surface and the terrestrial poles.
